Changes it so that -y displays the info in command and gui mode. This probably
should not be done for gui mode, as it stops the execution to display the
window, but I left it in anyway.
I'm using Mandriva Cooker, and every time I run "smart upgrade -y" I can't see
which packages will be upgraded. It just reads the cache, calculates the
transaction, and start downloading.
I suggest that it could show all the same infos as it would without using "-y".
